I have a Mac Book Pro (High Sierra 10.13.6), with an Intel I7 processor and an NVIDIA GeForce GT 750M Graphics card with the very latest drivers installed. My problem is that when I look at the Systems tab in Blenders preferences I cannot see any mention of CUDA under the 'cycles compute device'. My graphics card is there with a ticked checkbox, but I just have a 'None' or 'OpenCL' option above that. How do I get the CUDA option to appear, so that I can use my GPU to render instead of my CPU?

  • $\begingroup$ What happens if you choose OpenCL? Does that work? $\endgroup$ – Dale Cieslak Dec 24 '18 at 22:00
  • $\begingroup$ Fairly certain that's been a known issue in Blender for a long time. OpenCL is the only option available across all Macs so far as I know. I think it might actually be Apple's fault, but I'm not sure. $\endgroup$ – Kai Christensen Dec 25 '18 at 0:21
  • $\begingroup$ Do you have CUDA drivers installed with the nVidia Web driver? That was how I got it to work. $\endgroup$ – Samir Rahamtalla Dec 25 '18 at 7:32
  • $\begingroup$ Hi Dale, I'm not sure that I'm getting anything from the OpenCL option, but then I don't know what to look for! I can use Cycles in the same way I can on my PC, but so far I'm stuck with CPU rendering. $\endgroup$ – Jim Coote Dec 29 '18 at 13:57
  • $\begingroup$ Hi Samir, I've tried CUDA drivers from several sources including those downloaded from NVIDIA. I've now got the NVIDIA Driver manager installed. I would have hoped that using this would automatically ensure I was selecting the very best driver possible. Maybe I'm being naive! $\endgroup$ – Jim Coote Dec 29 '18 at 14:01
